The first of three in the series, The Book of Harry Potter Trifles, Trivias & Particularities, Volume 1 is designed for both the series' adult and YA audience. Nine Quests, organized by different aspects of J. K. Rowling's wizarding world will both challenge and delight the vast Harry Potter readership. Quiz material covers all SEVEN of the Harry Potter books, the two books J. K. Rowling wrote for charity (Fantastical Beasts and Where to Find Them and Quidditch Through the Ages) as well as information from her world-building website.

Each of the book's quests contain questions divided into three skill levels: Salamander, Phoenix, and Dragon (magical creatures of increasing size that are all associated with the element of fire). In a range of astrological systems around the world, fire is said to govern leadership, enthusiasm and competitiveness, making it a suitable theme for question difficulty and a way to keep the reader immersed in the fantastical. Future volumes will utilize this system with creatures that represent the elements of air (Volume 2) and water (Volume 3). Throughout the quest readers will be engaged by hint caption boxes and intriguing trivia tidbits including little-known historical facts referenced in the Harry Potter canon.

An answer key will be provided at the end of each quest, where readers can easily check their answers by question number. The source of the answer will be cited according to book and chapter number, due to the various editions on the market.
